Question

Let’s say I have method a() and method b() which both may throw an exception. In my program, there is a situation where I have to call at least one of them; it doesn’t matter which I call. However, if one of them throws an exception, I have to call the other one. If they both throw an exception, I don’t have to do anything.

I was thinking of doing something like this:

try {
    a();
catch (Exception e) {
    try {
        b();
    catch (Exception e) {

    }
}

but I thought this would be impractical if I had more than two methods to call. So I was wondering if there were a more elegant or better way to do something I’m trying to do.

Answer 1

you can

    abc:
    {
        try
        {
            a();
            break abc;
        }
        catch(Exception e){}

        try
        {
            b();
            break abc;
        }
        catch(Exception e){}

        try
        {
            c();
            break abc;
        }
        catch(Exception e){}

    }

if the chain is even longer, probably better

for(int i=0; i<4; i++)
{
    try 
    {
        switch(i)
        {
            case 0: a(); break;
            case 1: b(); break;
            case 2: c(); break;
            case 3: d(); break;
        }
    }
    catch(Exception e){} // next
}
